Interested to know how you all do you first cleans. Following the video on the Gardiner website Alex suggests on dirty frames to do the window in 2 stages, frames first, move on to next frame and so on then return to first and do the glass. Today I saw a video (Adders first clean) in which he suggests to scrub the frame and glass but don't rinse, move on to next window and return after a short while to the first window and then scrub and rinse frame and glass. Is there a difference or is it a personal choice. Would really appreciate your comments, thanks everyone.
